Firefighters in Toronto say they’re dealing with a massive spike in emergency calls, dealing with hundreds more urgent requests.

In a social media post, Toronto fire said its crews had been called to 622 emergency incidents in the city over the previous 24 hours.

They said that the figure was 41 per cent higher than typical call volumes for the service.

“Behind every call, our Call Takers and Dispatchers worked continuously to receive, prioritize, and support crews during this busy period,” the service wrote on social media.

Toronto fire did not give a reason for the increased call volume and did not respond to questions ahead of publication.
